15. Bella studies the role of grandmothers in the development of children by looking at differences between cultural groups in North America and Africa. Bella is most likely interested in which of the following theoretical issues in the study of human development?

Answer: C

Explanation:

Bella is most likely interested in universal versus context-specific factors.

Bella's research focuses on understanding the role of grandmothers in child development across different cultural groups, which aligns with the theoretical issue of universal versus context-specific factors. This perspective allows her to examine how cultural contexts influence developmental processes and the potential universality of certain developmental roles.

A) Proximal versus distal influences

This option refers to the distinction between immediate influences on development (proximal) and broader, more distant influences (distal). While Bella's study may involve both types of influences, her primary focus on cultural differences suggests she is more concerned with how these roles are perceived within varying contexts rather than the proximity of influences.

B) Nature versus nurture

Nature versus nurture pertains to the debate about genetic predispositions versus environmental influences on development. Although Bella's examination of cultural groups touches on environmental aspects, her specific interest in the role of grandmothers indicates a focus on contextual factors rather than the genetic versus environmental dichotomy.

C) Universal versus context-specific factors

This option is directly relevant to Bella's research, as she is investigating how the role of grandmothers varies across cultural contexts in North America and Africa. This approach highlights whether certain developmental influences are universal across cultures or specific to particular cultural settings, making it the most accurate choice.

D) Quantitative versus qualitative factors

This theoretical issue involves the distinction between numerical data and descriptive data in research. Bella’s focus on cultural differences in the role of grandmothers is likely to involve qualitative insights rather than a strict quantitative approach, meaning this option does not capture the essence of her research.

E) Continuity versus discontinuity

This concept addresses whether development is a gradual progression (continuity) or a series of distinct stages (discontinuity). While important in developmental psychology, this option does not directly relate to Bella's specific focus on cultural influences and the role of grandmothers.

Conclusion

In summary, option C is the best answer as it encapsulates Bella's interest in how the role of grandmothers in child development may vary across different cultural contexts. The other options, while relevant to broader developmental theories, do not specifically address the cultural aspect that is central to her research.
